  Fast, unopinionated, minimalist web framework for [node](http://nodejs.org). [![Build Status](https://secure.travis-ci.org/visionmedia/express.png)](http://travis-ci.org/visionmedia/express)

```js
var express = require('express');
var app = express();

app.get('/', function(req, res){
  res.send('Hello World');
});

app.listen(3000);
```

## Installation

    $ npm install -g express

 To install the 3.0 alpha:
 
    $ npm install -g express@3.0

## Quick Start

 The quickest way to get started with express is to utilize the executable `express(1)` to generate an application as shown below:

 Create the app:

    $ npm install -g express
    $ express /tmp/foo && cd /tmp/foo

 Install dependencies:

    $ npm install

 Start the server:

    $ node app

## Features

  * Built on [Connect](http://github.com/senchalabs/connect)
  * Robust routing
  * HTTP helpers (redirection, caching, etc)
  * View system supporting 14+ template engines
  * Content negotiation
  * Focus on high performance
  * Environment based configuration
  * Executable for generating applications quickly
  * High test coverage

## Philosophy

  The Express philosophy is to provide small, robust tooling for HTTP servers. Making
  it a great solution for single page applications, web sites, hybrids, or public
  HTTP APIs.
  
  Built on Connect you can use _only_ what you need, and nothing more, applications
  can be as big or as small as you like, even a single file. Express does
  not force you to use any specific ORM or template engine. With support for over
  14 template engines via [Consolidate.js](http://github.com/visionmedia/consolidate.js)
  you can quickly craft your perfect framework.
